. purposes; and the object of the invention is to produce ata smallercost and with less material as durable and useful bags as thoseheretofore made in the ordinary way. v

Water-bags ofthe particular description referred to are madesubstantially in whole .oflin r generally of pure rubher, and since,owing to the requirements of ordinary use, they must be capable ofwithstanding considerable'pressure without becoming much distended theyare made with comparatively thick walls to give them the necessarystrength.

My improvement consists in a water-bag of india-rubber having verticalor transverse bands or portions or both vertical and transverse bands orportions of greater thickness than the remaining parts of the walls, Inother words, my improved water-bag is in general distinguished by areticulated reinforcement of thicker rubber than the walls bf the bag,and this without regard tothe speeifie character of thestrengthening-bands or thickened portions, providing they be such as aswould a network for This form of, bag involves no additional expense inits making, while it requires for a bag of given size and strength lessmaterial than those made in the ordinary way.

In the drawings hereto annexed, Figure 1 is a side view of a water-bagembodying my I either by the overlapping of invention. Fig. 2 is across-section of the same on line a: w of Fi A is a bag of ordinaryform, generally made of two pieces ofisheet-rubber, whichare laid one onthe other, joined at their edges, and then vulcanized; Such bags areusually thickened along the lines of union of the two parts their edgesor by the application of a the loop or handle of the bag.

strip of rubber over the joint; sheet-rubber for the manufacture of myimproved bags I form or apply one or several bands or thicker portions"B, which extend entirely across the sides of directions, if sodesirechbut in any event so as to constitute a reticulated reinforcementfor the bag. When this is done, the thickness of the rubber sheet in thespaces between the reinforcing or thickened portions may be made so muchthinner without sacrifice of strength that the aggregate amount ofrubber necessary for a bag of given dimensions or capacity is reduced.

It is not necessary that the reinforcing portions should extend bothtransversely and vertically across the bag, but, as above stated, theyshould be so disposed to have the effect of a net, leaving comparativelysmall or narrow surfaces of the thinner wall between. An improved detailin-the construction of the bagis in using a single piece of rubber orrubber fabric for the reinforcement and r In other words, the loop ,orhandle 0 is formed by the por' tion of the part B where the latter isbent over and applied to the opposite sides of the bag. The two ends ofthe reinforcement B are lapped and pressed together at the bottom of thebag to form th tag I), in which the eyelet E is inserted.

What I claim is- 1,. A water-bag composed essentially of sheet-rubberwith a reticulated reinforcement composed of thickened portions of thewalls or sides of the bag, as set forth.

2. A water-bag A composed of sheet-rubber having bands or portions 13thicker than the remaining portions of the bag, extending but. inmolding or forming the the bag in several across its sides and servingas reinforcements therefor, as set forth. I I

A water-bag A composed of sheet-rubber having bands orreinforcing-strips B extending across its sides, the vertical band orstrip being extended above the neck of the bag to fori a loop or handle0 and united below the bag to form a tag D, as set forth. ADELBERT ll.ALDEN.
